I wrote it already to the 6.40.8 thread viewtopic.php?f=21&t=133585&p=676233#p676233, but with no response. I don't know if this problem is ROS or winbox related - has anyone seen/solved it too?
----------

There is probably a winbox (ROS?) bug in 3.11 and 3.16 with the new RB2011UiAS-2HnD r2 - LCD option is missing.

ROS 6.40.8, Winbox 3.11 & 3.16. RB2011UiAS-2HnD does have the option, the new RB2011UiAS-2HnD r2 does not.
LCD setting in terminal works, LCD itself too.

I have exactly this problem on 6.42.11 on live network. Did anyone got to the bottom of this?
